At the moment, Im using an Apple AirPort Express and a raspberry Pi for airplay. The Thing is that the AirPort is Way to expensive for just using airplay. The raspberry Needs to Long to Boot and i think its an Overkill.

With the due, we have some additional MHz to Start with. Did anybody try to Start with a Project yet? Any Status? Will this Even be possible? My Dream would be an arduino airplay with spdif Out
